Intelligent industrial mechanical arm for production line

The invention discloses an intelligent industrial mechanical arm for a production line, and belongs to the field of mechanical arms. An intelligent industrial mechanical arm for a production line comprises a fixed seat, a movable arm and a claw arm, the movable arm is installed on the fixed seat, the claw arm is installed on the movable arm, two sets of clamping claws are symmetrically arranged on the side wall of the claw arm in a sliding mode, a clamping rotating rod is rotationally connected to the claw arm, and a clamping motor is fixedly connected to the bottom of the claw arm; a workpiece is driven by the driving rotating rod to rotate, so that the workpiece is subjected to the friction action of the driving rotating rod, the polishing rotating rod, the positioning rod and the driven rotating rod at the same time, burrs, impurities and the like remaining on the surface of the workpiece are removed, the smoothness of the arc-shaped outer wall of the workpiece is effectively improved, and the quality of t
